first of all: I love blynk nearly everything on features that I need for my ideas is already implemented in blynk! Thats so nice!!!
actually I have different LED devices which are controlled by arduinos. The count of LEDs is different and the pattern are also different.
I like to control them over the air and synchronize them like the pattern or build large pattern over different devices.
So I tought about a mesh network but finally I think a star topology is fine because its fine with one controller.
With blynk I’m able to change the pattern, color, or any other thing of one device. Thats great!
Difficult is it for me to find a solution for sync and build modular groups.
Sync: I like to build larger pattern between multiple devices. So I have to identify them and give an order and give a difference between the other devices.
The goal is that: I have 3 devices. So I have to split 255 in to 3 parts and tell them. So: device1 get the information 0, device2 get the information 85 and device3 170.
I can set names for every device with an different auth key. It’s OK but not nice because I have to change every sketch. Better solution will be: generated names while running or similar which joining automatically with the same auth key.
Now I can use a tag for my 3 devices to set the pattern. OK
Now I have to count the devices and split 255 in the parts and send the information to 1, 2, 3… How? I’m able to count the devices and give different informations to them? I’m not able to programming on blynk app/server right?
When I have 4 more devices they should build a new group. If I like to do the same with them, I have to create a new widget and do the same like above right?
The goal should be to: select devices, or tags first AND then using the buttons and other stuff from the app. This is not possible actually. Any Idea to handle this?
